That test showed that alpha waves in the brain were boosted by the phone. This was also backed up by the fact the alpha wave boost was most significant in the brain tissue directly beneath the mobile phone. Alpha waves are generally associated with sleep and shifts in the attention of a person. Therefore, changes in alpha waves could also see changes in a person’s behaviour.

Overall the research found that mobile phones use frequencies that are good at affecting brainwaves and that the effect is the equivalent of drinking half a cup of coffee. It was also pointed out these results in no way show a health risk from using mobile phones.

It’s interesting to see research happening outside of the scope of “are phones bad for your health?”. In fact it turns out they can stimulate your brain and even suggests talking on a mobile phone can help you stay awake longer. I am in now way suggesting people start strapping phones to their heads when they need to stay awake, but if you have ever felt a bit rejuvenated when speaking on your mobile when tired; it could be in part due to the phone. I would suspect it is 99% to do with the interaction on the phone call, however.

In some ways this should act as a warning to research involving implanting electronic devices in our heads for whatever reason. The likelihood is that people who undergo such a procedure may end up having more trouble sleeping or be prone to more frequent behaviour changes, however small those changes are.
